Exploding Trousers
In New Zealand in the 1930s, farmers reportedly had trouble with exploding trousers as a result of attempts to control ragwort, an agricultural weed. Farmers had been spraying sodium chlorate, a government recommended weedkiller, onto the ragwort, and some of the spray had ended up on their clothes. Sodium chlorate is a strong oxidizing agent, and reacted with the organic fibres (i.e., the wool and the cotton) of the clothes. Reports had farmers' trousers variously smoldering and bursting into flame, particularly when exposed to heat or naked flames. One report had trousers that were hanging on a washing line starting to smoke. There were also several reports of trousers exploding while farmers were wearing them, causing severe burns. The history was written up by James Watson of Massey University in a widely reported article, "The Significance of Mr. Richard Buckley's Exploding Trousers" − which later won him an Ig Nobel Prize. On television In their May 2006 "Exploding Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Exothermic
In thermodynamics, an exothermic process () is a thermodynamic process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light (e.g. a spark, flame, or flash), electricity (e.g. a battery), or sound (e.g. explosion heard when burning hydrogen). The term ''exothermic'' was first coined by 19th-century French chemist Marcellin Berthelot. The opposite of an exothermic process is an endothermic process, one that absorbs energy usually in the form of heat. The concept is frequently applied in the physical sciences to chemical reactions where chemical bond energy is converted to thermal energy (heat). Two types of chemical reactions Exothermic and endothermic describe two types of chemical reactions or systems found in nature, as follows: Exothermic After an exothermic reaction, more energy has been released to the surroundings than was absorbed to initiate and maintain the reaction. An example would be the burn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pesticides In New Zealand
There is a high use of pesticides in New Zealand due predominantly to the large agricultural industry. Pesticides 1080 Sodium fluoroacetate, commonly known as 1080, is used in New Zealand to control animal pests, specifically the possum which threatens biodiversity and carries tuberculosus. Hunters fear that 1080 impacts on game animals, and some environmentalists have concerns about 1080 killing the very native fauna it is meant to save, and pollution of drinking water reservoirs with 1080 baits and poisoned animals. 2,4,5-T Manufacture of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) ceased in New Zealand in 1987 and it is no longer sold in New Zealand. 2,4-D 2,4-Dichlorophenoxyacetic acid (2,4-D) is used in New Zealand and the Pesticides Board has decided not to prohibit the use of the chemical. DDT DDT was used extensively for agricultural use in the 1950s and 1960s to control grass grub and porina moth. It was also used on lawns and for market gardens. Some 500 t ...

Explosions
An explosion is a rapid expansion in volume associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes Explosions can occur in nature due to a large influx of energy. Most natural explosions arise from volcanic or stellar processes of various sorts. Explosive volcanic eruptions occur when magma rises from below, it has very dissolved gas in it. The reduction of pressure as the magma rises and causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events and in phenomena such as hydrothermal explosions (also due to volcanic processes). Explosions can also occur outside of Earth in the universe in events su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture In New Zealand
In New Zealand, agriculture is the largest sector of the tradable economy. The country exported NZ$46.4 billion worth of agricultural products (raw and manufactured) in the 12 months to June 2019, 79.6% of the country's total exported goods. The agriculture, forestry and fisheries sector directly contributed $12.653 billion (or 5.1%) of the national GDP in the 12 months to September 2020, and employed 143,000 people, 5.9% of New Zealand's workforce, as of the 2018 census. New Zealand is unique in being the only developed country to be totally exposed to the international markets since subsidies, tax concessions and price supports for the agricultural sector were removed in the 1980s. However, as of 2017, the New Zealand Government still provides state investment in infrastructure which supports agriculture. Pastoral farming is the major land use but there are increases in land area devoted to horticulture. New Zealand is a member of the Cairns Group, which is seeking to hav ...

Going Over The Top
Trench warfare is a type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914.. Trench warfare proliferated when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage. On the Western Front in 1914–1918, both sides constructed elaborate trench, underground, and dugout systems opposing each other along a front, protected from assault by barbed wire. The area between opposing trench lines (known as " no man's land") was fully exposed to artillery fire from both sides. Attacks, even if successful, often sustained severe casualties. The development of armoured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hartlepool
Hartlepool () is a seaside and port town in County Durham, England. It is the largest settlement and administrative centre of the Borough of Hartlepool. With an estimated population of 90,123, it is the second-largest settlement in County Durham. Hartlepool is locally administrated by Hartlepool Borough Council, a unitary authority which also administrates outlying villages of Seaton Carew, Greatham, Hart Village, Dalton Piercy and Elwick. Hartlepool was founded in the 7th century, around the monastery of Hartlepool Abbey. The village grew in the Middle Ages and its harbour served as the official port of the County Palatine of Durham. After a railway link from the north was established from the South Durham coal fields, an additional link from the south, in 1835, together with a new port, resulted in further expansion, with the new town of West Hartlepool.

Edmund Blackadder
Edmund Blackadder is the single name given to a collection of fictional characters who appear in the BBC mock-historical comedy series ''Blackadder'', each played by Rowan Atkinson. Although each series is set within a different period of British history, each character is part of the same familial dynasty and is usually called Edmund Blackadder. Each character also shares notable personality traits and characteristics throughout each incarnation. In a 2001 poll conducted by Channel 4, Edmund Blackadder was ranked third on their list of the 100 Greatest TV Characters. Common characteristics Each Blackadder is positioned in a different place in British society over each series, with the character mostly falling in social rank through history. He moves from a prince (''The Black Adder'') to a lord (''Blackadder II''), a knight/baronet ('' Blackadder: The Cavalier Years''), a royal attendant (''Blackadder the Third''), a shopkeeper (''Blackadder's Christmas Carol''), to an army c ...

Blackadder Goes Forth
''Blackadder Goes Forth'' is the fourth series of the BBC sitcom '' Blackadder'', written by Richard Curtis and Ben Elton, which aired from 28 September to 2 November 1989 on BBC1. The series placed the recurring characters of Blackadder, Baldrick, and George in a trench in Flanders during World War I, and followed their various doomed attempts to escape from the trenches to avoid death under the misguided command of General Melchett. The series references famous people of the time and criticises the British Army's leadership during the campaign, culminating in the ending of its final episode, in which the soldiers are ordered to carry out a lethal charge of enemy lines. Despite initial concerns that the comedy might trivialise the war, it was acclaimed and won the British Academy Television Award for Best Comedy Series in 1989. In 2000 it was placed 16th by industry professionals in a list of the 100 Greatest British Television Programmes compiled by the British Film Insti ...

The Goon Show
''The Goon Show'' is a British radio comedy programme, originally produced and broadcast by the BBC Home Service from 1951 to 1960, with occasional repeats on the BBC Light Programme. The first series, broadcast from 28 May to 20 September 1951, was titled ''Crazy People''; subsequent series had the title ''The Goon Show''. The show's chief creator and main writer was Spike Milligan, who performed the series alongside Harry Secombe, Peter Sellers and (for the first two series) Michael Bentine. The scripts mixed ludicrous plots with surreal humour, puns, catchphrases and an array of bizarre sound effects. There were also light music interludes. Some of the later episodes feature electronic effects devised by the fledgling BBC Radiophonic Workshop, many of which were reused by other shows for decades. Elements of the show satirised contemporary life in 1950s Britain, parodying aspects of show business, commerce, industry, art, politics, diplomacy, the police, the military, educ ...

Australian Broadcasting Corporation
The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled after the British Broadcasting Corporation (BBC), which is funded by a tel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shock Wave
In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change in pressure, temperature, and density of the medium. For the purpose of comparison, in supersonic flows, additional increased expansion may be achieved through an expansion fan, also known as a Prandtl–Meyer expansion fan. The accompanying expansion wave may approach and eventually collide and recombine with the shock wave, creating a process of destructive interference. The sonic boom associated with the passage of a supersonic aircraft is a type of sound wave produced by constructive interference. Unlike solitons (another kind of nonlinear wave), the energy and speed of a shock wave alone dissipates relatively quickly with distance. When a shock wave passes through ...
